The difference between Bruno and guys like Arreola and Peter is how well they take a punch. Cris and Sam can dish it out AND take it.

Ray Mercer got outboxed by a Larry Holmes who never won another meaningful heavyweight fight ever again after beating Ray in 1992. There's the possibility that guys like Chmabers and Thompson bother him.

Ruddock was a more polished fighter than Arreola, but he did have trouble with his weight and he didn't take care of himself and whenever he stepped up he got beat....sound familiar?

As for Wlad being one dimensional...sure, but Wlad is in his prime and athletic enough to cut the ring off and there's no where/way to hide from him in the ring....with Foreman he was slower and if he got in vs a guy that would stick and move he would be in trouble...hell Tommy Morrison outboxed him easily.
